What is the story with 'M' and 'AO' as ratings? And how do they translate in terms of age? Someone once told me M is 17+ and AO is 18+, that can't be right surely? What's the difference in a year? Aside from being legally an adult of course.
In Europe we have 16+ and 18+ which I suppose are the equivalents. However games often get 18+ ratings, ones which tend to get an 'M', yet they still sell fine here and are stocked everywhere.
